#What never changes

Across states, Medicaid ABA programs converge on a few documentation pillars: medical necessity, time-accurate service logs, credentialed provider signatures, and a treatment plan linked to measurable goals. If any of those is weak, expect a clawback.

Session notes must reflect services billed — timestamps, units, procedures, and client response — or the record does not support payment.

#What varies

Authorization windows, supervision ratios, caregiver involvement requirements, and the acceptable format for signatures vary state to state.

Some states require caregiver training units each authorization period; others require specific progress-report templates; others are stricter on telehealth eligibility for direct service.

State Medicaid programs look similar until you get audited. Here is what holds up across states and what to double-check locally.

#The audit-ready records

If an auditor walked in tomorrow, you should be able to produce each of these within one business day.

  • Treatment plan and most recent progress report
  • Current authorization letter with units
  • Session notes for every billed date, with signatures
  • Supervision logs and fidelity checks (agency)
  • Caregiver training logs
  • BIP and any updates, with approval signatures

#How to stay ahead

Set a calendar reminder two weeks before every authorization expiration, and audit your own records the same day every month. State-specific surprises almost always come from template drift that went unchecked for a quarter.
